3. GENERAL DESCRIPTION
3.1 ASPIROTRONIC LE / ASPIROMEC LE WOOD FIRED BOILERS
FOREWORD
ASPIROTRONIC LE, ASPIROMEC LE,arewood fired boilers which operate on the reverse flame principle.
The flame is conveyed to the lower part of the boiler by the action of a suction device.
The flame develops in the burner referred to as LE. The configuration determines low emissions and an
exceptionally regular functioning. The LE burner satisfies the emission limit regulations in major European
countries, including Austria which has the strictest regulations concerning polluting emissions (art. 15a
B.V.G.).
THE BOILER CONSISTS OF :
1-FUEL BOX.This is where the gasification process (Pyrolysis) takes places, that is the reduction of the
wood moisture in simultaneous precombustion with the substances that take part in combustion. It is
normal for a layer of tar to be produced in proportion with the quantity of moisture content of the fuel.
2-LE BURNER.The shape of the burner and the materials used in its construction guarantee the creation
of a strong turbulence in the compartment under the burner. Veryhigh temperatures are developed in the
LE burner.The symbiosis between temperatureand turbulence guarantee low emissions.
3-COMBUSTION CHAMBER.The combustion chamber is located in the lowest part of the boiler and it
is the area on which the ash pan sits.
4-ASH PAN.The ash is deposited here.
5-SAFETY HEAT EXCHANGER.ASPIROMEC LE and ASPIROTRONIC LE can be fitted with a safety heat
exchanger.If a thermal relief valve is installed it absorbs the excess heat as soon as the boiler,due to
external causes, increases to excessively high temperature values. This function is referred to as the fast
disconnection phase. If necessary the heat exchanger can be used to produce hot water for domestic use.
Limit the duration of this function, as if it is used for a long period of time the boiler will cool down too much.
Furthermore, the removal of water must take place together with the operation of the boiler.
6-INSULATION.The thick layer of mineral wool enveloping the boiler and the insulated outer casing
panels guarantee that thermal dispersion is reduced to a minimum.
7-STARTER.Every time the loading door is opened it activates a direct communication between the fuel
box and the smoke outlet.

4.2 MOUNTING THE OUTER CASING ON ASPIROTRONIC COMBI LE.
- Mount the outer casing to the boiler as shown
in the figure on the previous page.
- Do not mount the top front panel (2); in its
place, mount the top rear panel (3) (For LE 102
COMBI use 2 brackets as the Eura boiler,
unlike the Aspirotronic boiler, is positioned
centrally).
- Disconnect the pins from the front panel and
fasten it to the rear panel.
- Fasten the bracket C to the EURA boiler (using
screws and nuts A)
- Position the Eura boiler as illustrated in the
figure and fasten it to the ASPIROTRONIC
boiler (using screws and nuts B).
- Position the EURA boiler and adjust the height
by acting on the screws which fasten the
bracket B.
- Wrap the mineral wool (5) around the boiler,
secure it using the fasteners provided and
make holes for the feeler pockets.
-Mount panels 1 and 3 (the plug must be at the
front); insertthem inside the 4 brackets on the
front panel of the boiler.
-Then mount panel 2 and secure the side panels
1and 3 using the screws provided.
-Lastly,fasten panel 4.

4- Board cover
5- Self-tapping screws
-Fasten the ASPIROTRONIC panel to the left side panel of the boiler. (If mounting it on the right side panel,
fix the control board by rotating it by 180° with respect to the panel. Alternatively, the panel can be affixed
to the wall).
-Fasten the cage nuts (1) provided in the precut holes.
- Unroll the capillaries and the thermocouple, thread them through the precut holes on the side panels.
Thread the end bulbs in the pockets (A) located on the top of the boiler and fill up with lubricating oil to
improve the heat exchange.
-Close the panel with the boardcover (4) using the screws and nuts (5).
- Insert the rear part and secure the front part with the catch.

INSTALLATION
page 13
The electronic panel is managed by a suitably programmed microprocessor.
The microprocessor not only improves the functioning of the boiler,
but it also makes it possible to manage the gas-diesel oil boiler with blown burner
of the EURA series.
The temperature detection system is controlled by one or two thermocouples
(combi version). The large display improves boiler management by making read-outs
and functions promptly available.
The main feature of the panel is its capacity to modulate the boiler power according
to the energy requirements of the plant. The panel allows the suction unit to vary its
speed according to the temperature of the boiler: the modulation of power is obtained
by reducing the speed of the smoke suction unit as the temperature in the boiler
increases.
THE PANEL CONSISTS OF:
• Main illuminated switch located on the back of the panel.
•Manual reset safety thermostat push button (back of panel); if the overtemperature
rises above 100°C the burner and fan are shut off.
Once the causes leading to the overtemperature have been identified and solved
the burner and fan can be reactivated by unscrewing the plastic cover of the
thermostat and pressing the button (the boiler temperature must be below 70° C).
• Signal light (back of panel); the light comes on to signal that the manual reset thermostat has tripped.
• Display.
•START push button (to start the operating cycle).
•MIN / MAX push button . Press the push button to select the MINIMUM CYCLE;the min. indicator light

4.7 ELECTRICAL CONNECTIONS DIAGRAM FOR ASPIROTRONIC LE
The circuitry consists of 3 terminal boards called M1 M2 M3. The individual contacts are called "pins".
TERMINAL BOARD M1
Pins 1-2-3 are used in the combi version with
the installation of a 3-way motorised valve
which can cut out and isolate the wood fuel
boiler when the gas-diesel oil boiler is
operating. The switch-over is done by means of
the special push button on the panel.
Pins 4 and 5 are used for the room temperature
thermostat of the plant circulating pump (pins 6
and 7).
The plant circulating pump will only be
activated under the following conditions:
-Room temperature thermostat with closed
contact.
- Temperature of the boiler above 61°C.
The power supply (220 V) for the plant
circulating pump is delivered from pins 6, 7.
The plant circulating pump also functions as a
thermal safety device: if the temperature in the
boiler rises above 90°Cthe plant circulating
pump is activated automatically.
TERMINAL BOARD M2
The M2 terminal board is used when a boiler
tube is installed for the production of hot water
for domestic use.
For priority to domestic hot water install a
thermostat connected to pins 1,2,4.
It is mandatory to connect all the contacts:
common, N.C., N.O.. Pins 3 and 5 are dedicated
to energising the boiler tube pump (220 V).
TERMINAL BOARD M3
Pins 1, 2 (220 V) are used for additional
circulating pumps.
The circulating pumps areonly activated if the
boiler temperature reaches or exceeds 61°C.
Pins 3 and 4 are used for the recycling pump
connected between the delivery and the return
(to prevent heat stratification of the water in the
boiler). This pump operates when the wood
fired boiler is active. Pins 5 and 6 (220V) are
used to power the gas-diesel oil burner.
Pins 7 and 8 are dedicated to powering the
suction unit.
Pins 9, 10, 11 are dedicated to an exchange
valve when the thermal safety device is
activated.

4.9 ASPIROMEC LE ELECTROMECHANICAL PANEL FUNCTIONS
The control panel consists of the following parts:
1 – Main and cycle start switch (illuminated).
2 – Boiler fan control switch.
3 – Heating plant circulating pump control switch.
4 – Wood cycle start and fuel finished signal light. This light comes on when the
fuel finished thermostat signals a drop in the water temperature caused by
a lack of firewood. The thermostat is located inside the electric panel and it
is calibrated at 45° C. Once the wood load finishes the light comes on and
the fan shuts off.
5 – Manual reset safety thermostat; when the overtemperature goes above 100°
C the fan shuts off. Once the reasons for this overtemperature have been
identified and resolved the fan can be reactivated by unscrewing the plastic
cover on the thermostat and pressing the button (the temperature of the
boiler must be below 70° C).
6 – Thermostat for regulating the boiler water temperature (from 70 to 90° C).
The manufacturer recommends keeping the boiler water temperature on
high values (75° C /80° C) in order to prevent the formation of condensation.
7 – Thermometer.
The following devices are located inside the electric panel:
- Forced circulation (bypass) thermostat calibrated at 90°C. This is a safety
device which prevents the boiler water from boiling by activating the
circulating pump for a few seconds, even without the signal from the room
temperature thermostat.
- Anticondensation thermostat (Calibrated at 60°C)
- Fuel finished thermostat (Calibrated at 45°C)
- Relay.
Operation:
The operation of the fan is indispensable for intaking air required for the combustion in the boiler. The fan
functions if switch 2 is positioned on "1".
The air intake is always the maximum and it only stops when the set point temperature of the boiler
thermostat is reached. The pumps must always be connected to the panel as they are activated above
60°C. When the wood fuel is about to finish, the water temperature tends to drop and eventually shuts down
the pump as the anticondensation thermostat is tripped. The fan continues to operate without producing
any further heat and cools the boiler body. When, as a result of this cooling process the temperature drops
to roughly 45°C, the fuel finished thermostat is tripped, which in turn shuts down the fan. In the initial
starting phase when the boiler is cold the fuel finished device could be activated even if the boiler is lit and
running on a full load of wood.
This occurs when:
- The circulators are not connected to the electric board but by means of external collar thermostats. The
poor sensitivity of these thermostats can allow the pumps to operate to the point where the water
temperature in the boiler drops below 45°C which trips the fuel finished thermostat.
- The overall capacity of the pumps is so high that when they start at 60°C for the first time, the water refill
is so fast that the cold water return from the plant is not signalled in time by the anticondensation
thermostat, consequently the temperature drops below 45°C, which in this case as well, trips the fuel
finished thermostat.
To remedy this situation in this case simply reduce the pump speed, or throttle its flow capacity.
